Impossible to leave fullscreen mode on touchscreen desktop without keyboard

[klues]

Currently there are the following possibilities to leave fullscreen mode:

• Press Esc on keyboard
• Swipe down from top on mobile platform

There should also be a possibility to leave fullscreen without keyboard on desktop.

Leave fullscreen through an element/button that does that action. No swiping, no esc.

I've added the possibility to enter/leave fullscreen via the new System action. Also released to "latest", test it with the configuration from this comment, where I've also added elements to enter/leave fullscreen to the global grid.

Awesome, it works, thank you!
